Changing xml in LiveCycle to enable pdf email submit

I've read quite a a bit about my question.  Which is:  can I change the xml code in LiveCycle of an interactive pdf to make it work when displayed in a browser?  I've read

Form submit / eMail demystified, but quite honestly I cannot quite grasp it.  I did find people asking the question in another forum and someone posted the following: "

What I finaly did:

Found the line:

<submit format="xml" textEncoding="UTF-8" target="mailto:"/>

changed it to:

<submit format="pdf" textEncoding="UTF-8" target="mailto:"/>

resaved document, and it worked."

This post was a few years old however.  I tried it and my code looks like this:

<submit textEncoding="UTF-16" xdpContent="pdf datasets xfdf" format="pdf" target="mailto:

I'm assuming because it's a newer version of Acrobat.

Can anyone tell me what I would need to change my code to in order for the email submit button to work, or if it indeed will require me to find someone to script something for me.

Thanks,

Scott
